Problem of faith listen here
Christianity is often perceived as fideism; that is belief in something despite its irrationality or absurdity. Contrary to this the bible calls us to reason (Isa 1:18), to love God with all our mind (Matt 22:37), to know things with certainty (Luke 1:3-4)
The bible also says that we have not followed cunningly devised fables, but have heard from God, who cannot lie (Heb 6:18), with a sure word of prophesy (2 Pet 1:21).
Biblical faith is not irrational. God never demands us to believe in something illogical (1 John 1:1-3), but to believe in the coherent propositions of the scripture (Rom 10:9-13). This is the true challenge to unbelief; to believe that Christ is only unique savior of mankind (Act 4:12). The unbeliever’s unbelief is not rooted in an intellectual difficulty with Christian Theism, but rather it is a moral failure to repent and believe the *truth*(John 3:19).
